Definitions

  • the invention relates to a jug with a temperature indicator, and more particularly, but not exclusively, to a jug with a temperature indicator which is suitable for steaming milk in the process of preparing coffee for consumption.
  • U.S. Pat. No. 6,324,963 and Australian Patent No. 2009101190 have proposed milk frothing jugs with temperature indicators, however the applicant has identified that the utility of these previously proposed jugs is quite limited, and that the longevity may also be limited. More particularly, with reference to Australian Patent No. 2009101190, the milk frothing jug has a temperature indicator which indicates milk inside the jug being brought to only a single specific temperature. Also, the temperature indicator is attached to the jug in the form of a label which will deteriorate over time and will be likely to be separated from the jug through repeated use of the jug and repeated dishwasher cycles.
  • Examples of the present invention seek to provide a jug with temperature indicator which overcomes or at least alleviates one or more disadvantages associated with previous milk frothing jugs.
  • a multi-purpose jug with temperature indicator wherein the jug is formed from a material having high thermal conductivity, including a liquid crystal thermometer attached to a side of the jug, the thermometer being arranged to indicate temperatures of liquid within the jug from 35 degrees Celsius to greater than 65 degrees Celsius, wherein the liquid crystal thermometer is in the form of a label adhered to the external side of the jug and is sealed with a layer of resin covering the label.
  • the material is stainless steel.
  • thermometer is arranged to indicate temperatures of liquid within the jug from 35 degrees Celsius to 85 degrees Celsius.
  • the liquid crystal thermometer has a series of separate cells which indicate specific temperatures in predetermined intervals.
  • a method of using a multi-purpose jug as described above including the steps of heating/cooling water in the jug using the liquid crystal thermometer to bring the water to a temperature of approximately 35 degrees Celsius for making dough, and steaming milk in the jug using the liquid crystal thermometer to bring the milk to a temperature of approximately 65 degrees Celsius.
  • FIG. 1 is a side view of a jug with temperature indicator in accordance with an example of the present invention
  • FIG. 2 is an opposite side view of the jug shown in FIG. 1 ;
  • FIG. 3 is a detailed view of the temperature indicator of the jug shown in FIGS. 1 and 2 ;
  • FIG. 4 is a detailed cross-sectional view of the temperature indicator attached to the jug, in accordance with one example
  • FIG. 5 is a detailed cross-sectional view of the temperature indicator attached to the jug in accordance with another example
  • FIG. 6 is a detailed cross-sectional view of the temperature indicator attached to the jug in accordance with yet another example.
  • FIG. 7 is a detailed view of a lower portion of the jug shown in FIGS. 1 and 2 .
  • a jug 10 with a temperature indicator 12 which is suitable for frothing milk in the preparation of coffee beverages for consumption.
  • the jug 10 is formed from a material having high thermal conductivity, and includes the temperature indicator 12 in the form of a liquid crystal thermometer 14 attached to an external side of the jug 10 .
  • the thermometer 14 is arranged to indicate temperatures of liquid within the jug 10 from 35° C. to greater than 65° C.
  • the liquid crystal thermometer 14 is in the form of a label adhered to the external side of the jug 10 , and is sealed with a layer of resin 16 covering the label.
  • the material of the jug 10 is stainless steel, which has high thermal conductivity such that the temperature of the liquid within the jug is readily transmitted to the liquid crystal thermometer 14 such that the temperature shown on the thermometer 14 is accurate.
  • the example depicted in the drawings has the liquid crystal thermometer 14 arranged to indicate temperatures of liquid within the jug 10 from 35° C. to 85° C. More specifically, the liquid crystal thermometer 14 has a series of separate cells 18 which indicate specific temperatures in predetermined intervals. The arrangement shown has sufficient cells 18 to indicate temperatures in 5° C. intervals from the lower bound of 35° C. to the upper bound of 85° C., with each cell being associated with a specific temperature. However, due to the nature of operation of the cells 18 , temperatures within each interval can be identified by the change in appearance, particularly in the change of colour, of the neighbouring cell or cells 18 .
  • the jug 10 is also useful for identifying the correct temperature of steamed milk for the preparation of coffee beverages, which has been found to be in the order of 65° C.
  • FIG. 3 shows a detailed view of the liquid crystal thermometer 14 in which the cell 18 a associated with the temperature of 60° C. may be represented in a different colour, or may change to a different colour, so that the user can readily identify that the frothed milk is at the correct temperature.
  • the cell associated with the temperature of 35° C. and/or the cell associated with the temperature of 40° C. may be coloured differently so that the user may also readily identify the correct temperature in the preparation of water for making dough.
  • the liquid crystal thermometer 14 may be labelled with a brand such as “Latte pro”, as shown.
  • FIGS. 4 to 6 show different examples of detailed cross-sectional views of attachment of the liquid crystal thermometer 14 to the jug 10 .
  • a layer of resin 16 is used to cover the liquid crystal thermometer 14 so as to prevent it from being removed during repeated cycles of use of the jug 10 , which will include fluctuations in temperatures and harsh conditions, particularly in dishwashers.
  • the liquid crystal thermometer 14 is housed within an indentation 20 formed in a side of the jug 10 with the layer of resin 16 being applied over the liquid crystal thermometer so as to be flush with the surrounding surface of the jug 10 .
  • the jug 10 is provided with a stainless steel frame 22 which surrounds and protects the liquid crystal thermometer 14 .
  • the resin 16 is formed in a layer which is flush with the surrounding frame 22 .
  • the liquid crystal thermometer 14 is applied to the side of the jug 10 , without an indentation or a frame 22 .
  • the liquid crystal thermometer 14 is covered by a layer of resin 16 which extends over each extremity of the liquid crystal thermometer 14 so as to protect the thermometer 14 from inadvertent removal.
  • FIG. 7 shows a detailed side view of a lower portion of the jug 10 with the liquid crystal thermometer 14 attached.
